Partition Action in California: What Los Angeles Co-Owners Need to Know
When co-owners of an LA property disagree on selling, any owner can force a sale under California law. Here's how partition actions work and what they cost.
Can a co-owner force the sale of a jointly owned property in California?
Yes. Under California Code of Civil Procedure §872.010, any co-owner of real property has the right to force a division or sale of that property through a court action called a partition. In Los Angeles, where partition actions most often arise from inherited estates, ended partnerships, or relationships that have broken down, courts almost always order the property sold rather than physically divided. The proceeds are then distributed to each owner in proportion to their ownership interest, minus attorney fees, referee fees, and other costs of the proceeding.

When siblings inherit a Beverly Hills home and one wants to cash out while the other wants to keep it, there's no easy middle ground. The same situation plays out across the Hollywood Hills and Bel Air regularly: former domestic partners who bought together, investment partners with incompatible timelines, adult children who can't agree on what to do with a parent's estate. If everyone involved can't reach an agreement, California law gives any one of them a powerful option.
It's called a partition action, and it can result in a court ordering the sale of a property whether the other co-owners agree or not.
Here's what you need to know before you file, or before you receive a filing.
What is a partition action?
A partition action is a lawsuit filed in the Superior Court of the county where the property is located. In Los Angeles County, that means LA Superior Court.
Any co-owner, regardless of what percentage they own, has the right to file. California's partition statute treats this as an essentially absolute right. A co-owner cannot be contractually prevented from filing a partition action in most circumstances, though they can agree in writing to delay one for a reasonable period.
There are two possible outcomes:
Partition in kind divides the property itself between the co-owners. For single-family homes, which cannot be physically divided into separate parcels, this option is almost never available.
Partition by sale means the court orders the property sold and the net proceeds distributed. This is what happens in virtually every residential partition case in Los Angeles.
How the partition process works
Once a petition is filed and served on all co-owners, the case follows a fairly predictable path:
- The petition is filed and served. All co-owners must be formally notified.
- The court determines ownership interests. If the co-owners don't agree on who owns what percentage, the court resolves it.
- An interlocutory judgment of partition is entered. This preliminary order establishes that the partition will proceed and sets the terms.
- A partition referee is appointed. The referee, typically a real estate professional or attorney, is tasked with managing the sale. They hire a broker, list the property, and oversee the transaction.
- The property is listed and sold. The sale process looks much like any other listing, but the seller is effectively the court.
- Proceeds are distributed. After the referee and attorneys are paid, the remaining proceeds go to the co-owners in proportion to their ownership interests.
From filing to final distribution, the process typically runs 12 to 24 months for contested cases. Uncontested situations can move faster.
What the costs actually look like
A court-ordered sale is not free, and the costs come out of the proceeds before anything is distributed. Here is what typically reduces the net:
- Attorney fees: Both sides usually retain counsel. Depending on how contested the case becomes, this can range from tens of thousands of dollars into six figures on high-value properties.
- Partition referee fees: The referee charges for their time managing the sale. Typical fees run 1% to 2% of the sale price. On a $4 million Bel Air estate, that's $40,000 to $80,000.
- Court costs and filing fees: Relatively modest, but real.
- Real estate commissions: The referee hires a broker, and standard commission rates apply.
- Carrying costs: While the case is pending, property taxes, insurance, and any mortgage payments continue. These can become additional disputes if co-owners disagree on how to split them.
On a $3 million property, combined costs of $200,000 or more before the proceeds are divided is realistic in a contested case. This breakdown of what sellers typically walk away with at closing in LA is a useful starting point, though partition sales add a layer of legal costs on top of standard seller expenses.

The alternative: buyout or private agreement
The most effective way to avoid a partition action is to reach a private agreement before anyone files.
The most common outcome is a buyout: one co-owner purchases the other's interest at a negotiated price. The valuation is usually the sticking point. An independent appraisal can establish a baseline, but both parties need to agree on the process and the number.
If neither party wants to buy the other out, a voluntary listing agreement accomplishes the same end goal as a partition action at a fraction of the cost and in far less time. A market-rate sale through an agent typically closes in 60 to 90 days. A partition action through the courts takes 12 to 24 months or more, and that gap represents real money in carrying costs and legal fees that come directly out of everyone's share.
The calculus is straightforward: private resolution saves both time and money. The partition process is what happens when private resolution fails.
A note on heirs property in California
California adopted the Uniform Partition of Heirs Property Act (UPHPA) in 2022. For inherited property, this law adds several protections:
- Before the court can order a sale, the other heirs must be given notice and an opportunity to purchase the filing co-owner's interest at a court-appraised fair market value.
- The court must obtain an independent appraisal of the property.
- The court weighs additional factors, including whether the property has served as a family primary residence, before ordering a sale.
The UPHPA does not prevent partition actions involving inherited property. It adds procedural steps designed to prevent low-value court sales of family homes and give heirs more control over the process.
Measure ULA and partition sales in Los Angeles
For co-owners of high-value Los Angeles properties, Measure ULA applies to partition sales just as it does to any other transfer. There are no exemptions for court-ordered sales.
If the property sells above the current threshold (4% at $5.4 million and above, 5.5% at $10.9 million and above, with tiers indexed annually), the ULA transfer tax is deducted from the proceeds before distribution. On a $7 million Bel Air estate, that's an additional $280,000 coming out of the proceeds, split among the co-owners.
For co-owners navigating a potential partition at these price points, the transfer tax makes a voluntary pre-sale agreement even more financially compelling. LA's documentary transfer tax structure is worth understanding in detail before any sale, court-ordered or otherwise.
Frequently Asked Questions
Can a co-owner refuse to participate in a partition action?
A co-owner cannot block a partition action from proceeding. California courts treat the right to partition as essentially absolute for any co-owner. A co-owner who refuses to cooperate can slow the process by contesting ownership percentages or raising other disputes, but they cannot prevent the court from ultimately ordering a sale.
What happens to a mortgage on a property in a partition action?
Any outstanding mortgage is paid off from the sale proceeds before the co-owners receive their shares. The partition proceeding does not extinguish the lender's lien.
Can co-owners settle a partition action after it has been filed?
Yes, and many do. A voluntary settlement, whether a buyout or a mutual agreement to list the property, can be reached at any point during the case. Settling after filing still means attorney fees have been incurred on both sides, which is one reason early resolution is worth pursuing seriously.
Does a partition sale go through the MLS?
Usually, yes. The partition referee typically lists the property with a licensed real estate broker, and it goes on the open market like any other listing. The property can also be sold by public auction, but open-market listings generally achieve better prices.
Is partition available for properties held in a trust or LLC?
It depends on the structure. If property is held in a living trust and has not yet been distributed to heirs, probate court may have jurisdiction rather than the standard partition statute. For property held in an LLC, the partition statute may not apply directly, and the dispute could turn on the operating agreement instead. Both situations call for specific legal counsel before any action is taken.
If you're dealing with a co-ownership situation on an LA property, whether that means an inherited estate, a partnership that has run its course, or simply a disagreement about timing, the most important first step is understanding what your options actually cost. Litigation is rarely the fastest or cheapest path, and in many cases, a clear market analysis and an honest conversation are all it takes to find common ground.
